| 707651000 | Hierarchical backup | 9 |
| 20110119235 | HIERARCHICAL SYSTEMS AND METHODS FOR PERFORMING DATA STORAGE OPERATIONS - The invention is a hierarchical backup system. The interconnected network computing devices are put into groups of backup cells. A backup cell has a manager software agent responsible maintaining and initiating a backup regime for the network computing devices in the backup cell. The backups are directed to backup devices within the backup cell. Several backup cells can be defined. A manager software agent for a particular cell may be placed into contact with the manager software agent of another cell, by which information about the cells may be passed back and forth. Additionally, one of the software agents may be given administrative control over another software agent with which it is in communication. | 05-19-2011 |
| 20120117029 | BACKUP POLICIES FOR USING DIFFERENT STORAGE TIERS - Systems and methods of using different storage tiers based on a backup policy are disclosed. An example of a method includes receiving a backup job from a client for data on a plurality of virtualized storage nodes. The method also includes identifying at least one property of the backup job. The method also includes accessing the backup policy for the backup job. The method also includes selecting between storing incoming data for the backup job on the plurality of virtualized storage nodes in a first tier or a second tier based on the backup policy. | 05-10-2012 |
| 20130218842 | STORING A VARIABLE NUMBER OF INSTANCES OF DATA OBJECTS - Described are systems and methods for storing a variable number of instances of data objects (e.g., 1, 2, 3, or up to N−1 instances, where N is the number of instances of the data object included in primary data) in secondary storage across a data storage network. In some examples, a system for storing a variable number of instances of data objects includes, one or more computing devices storing a set of data objects and multiple storage devices distinct from the one or more computing devices. Each of the multiple storage devices is configured to store at least a single instance of a data object. The system also includes a database configured to store information associated with the data objects. This information includes substantially unique identifiers for the data objects and, for each of the data objects, a number of instances of the data object stored on the multiple storage devices. | 08-22-2013 |
| 20130246365 | METHODS AND SYSTEMS FOR SEARCHING A BACKUP VOLUME - Methods and systems for searching a backup volume use, in one embodiment, a move marker file to indicate attributes for a new name space and optionally indicate attributes for a prior name space of a directory on a source volume, the directory having been moved between backup snapshot operations in which data on the source volume is backed up to the backup volume. Other embodiments are also described. | 09-19-2013 |
| 20130282663 | PRESENTING A FILE SYSTEM FOR A FILE CONTAINING ITEMS - What is disclosed is a volume access system. The volume access system includes a processing system configured to process at least a portion of each of a plurality of virtual disk files to generate an aggregate file system view that represents the plurality of virtual disk files as a single hierarchical data volume comprising a plurality of items within the plurality of virtual disk files. The volume access system also includes a network interface operatively coupled with the processing system and configured to communicate the aggregate file system view for traversal by a plurality of clients. | 10-24-2013 |
| 20140201156 | VIRTUAL MACHINE FILE-LEVEL RESTORATION - Disclosed is a method and system for selectively restoring file-level data from a disk image backup. In embodiments, a virtual machine backup may be performed by dividing a virtual machine virtual disk file into a plurality of discrete fixed-sized data blocks sharing a common index file that is stored on a backup medium, such as a hard drive, to form a backup set. The index file is referenced to determine which fixed-sized block contains volume information, such as a partition table, of the backed-up virtual machine file. The individual blocks are processed as a virtual filesystem which is mounted and presented to an access module, which traverses the filesystem and provide access to individual files in the image backup to a client process. The restore files may be delivered to the client in a container file, which may be compressed to increase transfer speed. The container file may include executable instructions for automatically restoring the files to a desired location. | 07-17-2014 |
| 20150052109 | NETWORK-BACKED FILE SYSTEM - Methods and systems for implementing a network-backed file system are disclosed. Data indicative of a plurality of subscriptions by a plurality of clients to respective subsections of a file system is stored. The subscriptions comprise one or more read subscriptions and one or more write subscriptions. The read subscriptions are fulfilled by sending modified file chunks of subsections to subscribing clients. The write subscriptions are fulfilled by modifying file chunks of subsections based on write requests submitted by subscribing clients. | 02-19-2015 |
| 20150058296 | DATA STORAGE METHOD AND COMPUTING DEVICE USING SAME - A data storage method for a computing device is disclosed. The method includes: receiving, at a computing device, a file and a profile, wherein the profile includes a level of magnitude; storing, at the computing device in a first database, the file if the level of magnitude is greater than the lowest level; storing, at the computing device in a second database, the file if the level of magnitude is the highest level; and deleting, at the server, the file if the level of magnitude is the lowest. | 02-26-2015 |
| 20160019118 | PRESENTING A FILE SYSTEM FOR A FILE CONTAINING ITEMS - What is disclosed is a method of operating a volume access system. The method includes processing at least a first file to generate a file system view of the first file comprising a plurality of items within the first file, and providing the file system view of the first file over a network interface as a hierarchical data volume. The method also includes receiving an access request for a requested item of the hierarchical data volume over the network interface, and in response, providing access to a first item of the plurality of items within the first file corresponding to the requested item. | 01-21-2016 |
